Title: Vertical shaft type pump
Inventor: TAKEMOTO YOSUKE
IPC: F04D15/00
Filed: 1989-07-28
Abstract: PURPOSE:To enable a full-speed waiting operation so as to prevent any flood due to an abnormal increase in water level or any operational faculty of a pump due to an abnormal decrease in water level by setting the upper opening end of a bent pipe, the bending point of the bent pipe, and the bending portion of a branch pipe at predetermined levels, respectively. CONSTITUTION:A U-shaped bent pipe 11 extends from the suspension portion 10 of a U-shaped branch pipe 3 connected to a suction casing 2 communicated with an impeller chamber 6, and the upper opening end 12 of the bent pipe 11 is set above the lowest water level LWL of a vertical shaft type pump. A level of a bending point 13 of the bent pipe 11 is set between a level of the upper opening end 12 and the lowest water level LWL, and the U-shaped bending portion 8 of the branch pipe 3 is set at a position higher than a suction pumping level due to the maximum negative pressure generated in the impeller chamber 6. With this constitution, a certain difference in level can be kept between a pumping start level from an aerial operation and the lowest water level to transfer from the pumping operation to the aerial operation while maintaining a full-speed waiting operation performance, thereby preventing any generation of hunting phenomenon at the time of pumping stop.

Abstract: PURPOSE:To form a power MOS FET having a high withstand voltage and moreover enabled to reduce ON resistance by a method wherein resistivity of the surface layer of the circumferential part of a substrate is made higher than the central part to act as an active region. CONSTITUTION:To the surface of a high resistivity n type Si substrate 1 formed with an n<+> type diffusion layer 2 on another main surface of the substrate, reversely conductive type impurity ions B are implanted at extremely low concentration to the surface of the circumferential part of the substrate to be diffused using an SiO2 film 14 as a mask, and a more high resistivity layer 13 is formed. Then p type wells are diffused through a mask formed by etching and removing a part of an SiO2 film 15, and p type layers 3, 6, 7 are formed. A shallow p type diffusion layer 3a to act as a channel part is formed around the p type well layer 3. After then, the SiO2 film at the central part is etched to be removed, and a thin gate SiO2 film 16 is formed according to thermal oxidation. Then Si is deposited to form poly-Si layers 5, 5a, photoetching is performed to form a part thereof as a gate, and after then, an n<+> type source 4 is formed by selfalignment under the gate SiO2 film using the poly-Si layers 5, 5a as masks. The poly-Si layer 5a at the central part of the p type layer 3 is removed thereafter.

Title: Magneto-optical reproducer
Inventor: SO KOJI
IPC: G11B11/10
Filed: 1986-08-22
Abstract: PURPOSE:To enable detection of signals without deterioration by disposing a 1st cylindrical lens and 2nd cylindrical lens on the same optical axis, and disposing the respective focal positions so as to be brought on the same photodetector. CONSTITUTION:Polarization direction 30 of the incident parallel light on a half wavelength plate 12 is rotated 45 deg. by the plate 12 to a deflection direction 31 which is parallel with the axial direction of the 1st cylindrical lens 28. The 1st cylindrical lens has curvature only in the direction perpendicular to the polarization direction; therefore, the polarization to the elliptical polarized light by a difference in the refractive index between P polarized light and S polarized light by the material quality of the lens is obviated and the light is focused perpendicularly to the plane of polarization on the photodetectors 16, 17. The 2nd cylindrical lens 29 is so formed that the axial direction is perpendicular to the polarization direction 31 and the focal position thereof rides on the same phase plane of the incident beam on the axis on the photodetector. The polarization of the exit light to the elliptical polarized light by a difference in the refractive index between the P polarized light and the S polarized light is, therefore, obviated and said light is focused in the polarization direction on the photodetectors 16, 17. The good reproduction signal is thereby obtd.

Title: Flat material sorting device for stacking device
Inventor: UCHIMURA KAZUO
IPC: B65H33/18
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To perform stable stacking and downsize a device by temporarily constraining a blade shaft of a blade adjacent in a position, reverse to the rotating direction of a rotating main shaft, to a blade set into a position of receiving flat material from a conveying device. SOLUTION: Rotors 3, 4 disposed around a rotating main shaft 2 are integrally rotated, and blade shafts 3b, 4b connected to the rotors 3, 4 are also rotated in the same way so as to rotate blades 10, 11 around the rotating main shaft 2. With the rotation of the rotating main shaft 2, the rotors 3, 4 are continuously rotated integrally with the rotating main shaft 2, but when the position of the blade 11 is detected by a proximity switch 14, a cylinder is driven by a control device to advance a rod, and a hook 13 is caught by a blade shaft 4b on the rod 4 side so as to constrain the blade shaft 4b. Accordingly, even if flat material has large weight, this has no influence on the rotation of the rotating main shaft 2, the attitude change of the blades 10, 11, and the like.

Abstract: PROBLEM TO BE SOLVED: To improve the space efficiency by providing a rotation regulating means regulating the rotation of a correction means around an optical axis (rolling direction) on the back surface of a bottom board. SOLUTION: The correction means consisting of a correction lens 11 and a supporting frame 12 is driven in a pitch direction 114p and a 78W direction 114y by a driving means consisting of a permanent magnet, etc., so that image blurring is corrected.
